SODA-WATER FOUNTAIN.

SPECIFICATION forming part of Letters Patent No. 443,683, dated December 30, 1890.

Application filed April 23,1890. Serial No, 349,131. (No model.)

.To all whom, it may concern:

Be it known that I, WILLIAM HENRY MAR- SHALL, of Chelsea, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in SodaWVater Fountains, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science towhich said invention appertains to make and use the m same, reference being had to the accompanying drawings, forming part of this specification, in Which Figure 1 is aplan view showing my improvement; Fig. 2, a vertical transverse section of two of the annular cylinders, showing the details of construction; and Fig. 3, a perspective view of the lower section of one of said cylinders.

Like letters of reference indicate correzo sponding parts in the different figures of the drawings.

Myinvention relates especially to mechanism for cooling charged or carbonated water in soda-fountains as it is received from the 2 5 supply-tank; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the case or 5 body of the fountain, which may be of any suitable form and construction.

A series of annular cylinders 13 G D E F G H I K are disposed in the bottom of the body A and are packed around with ice in the same manner as the ordinary pipes in a SOtlfirfOlliltain. These cylinders are constructed of two cup-shaped sections 7) cl, having central openings g, rimmed or secured together at f,forming a hollow or cylindrical shaped ring or 5 torus. .A horizontally arranged pipe or tube h passes through the wall of the lower section (Z and connects adjacent cylinders together. One end 1' of said tube is bent or curved within the cylinders around their central portion j, the discharge mouth or end on thereof being beveled outwardly, as best shown in Fig. 1, to direct the liquid discharged therefrom against the outer Wall of the cylinder. The opposite or receiving end 19 of each tube is disposed in an adjacent cylinder and bent vertically upward and opening under the top of the upper section b of said cylinder, as best shown in Fig. 2. Each pairor set of annular cylinders is connected by an independent pipe h. Said cylinders are arranged in series, as shown, the last cylinder K of the series being disposed centrally in the bodyA and enlarged. The discharge h, leading from said cylinder, projects through the front Wall of the fountain and is provided at its outer end with the ordinary tap or faucet t. The tube h, leading into the first cylinder B of the series, projects through theside wall or bottom of the fountain and is connected with a supply-tank containing the charged water. The water in the tank being under high pressure, as soon as the faucet t is opened is driven with great force through the tube It into the first annular cylinder B, and being directed by the tube against the wall of said cylinder inpinges and 7 5 circulates rapidly therethrough. Thence it passes into the mouth p of the companion tube into the next cylinder of the series, circulating in said cylinder and passing in like manner through each cylinder of the series until discharged from the faucet. \Vhen said faucet is closed, the cylinders remain filled with the water. By the construction described the cylinders present a large surface to the action of the ice. The carbonated water being driven 8 5 with great force into the cylindersby thepress ure in the tank is violently agitated as it im* pinges from the walls of said cylinders. This causes the temperature of the Water to rapidly lower, it being delivered to the faucet at a temperature of about 33 Fahrenheit, or approximately at the freezing-point of Water. Moreover, by thus violently agitatingthe water in the cylinders the carbonic-acid gas with which it is charged is more evenly distributed 5 therethrough, requiring a much longer time to escape from the water when free in the glass than when drawn directly from the tank through coiled tubes or pipes in the ordinary manner.
